Both appear to have (limited) HVEC decoding capabilities IF and only IF the OS has an appropriate driver for it. Otherwise there is no hardware decoding and no game on anything above 1080p.

Question: does LibreELEC have the necessary drivers to call on these SoC's (limited) HVEC decoding capability?

N3060 has Intel HD 400 (braswell)

Z3735F has Bay Trail

Question: has anyone sucessfully played HVEC on either of these SoC's with LibreELEC ? And if so, does one need to get any specific drivers for it to work? Linux VLC on these does not play nice with HVEC (I tried, unwatchable)
